Drug metabolism and disposition: the biological fate of chemicals, 42(4), 774-781 (2014-01-29)
3-n-Butylphthalide (NBP) [(±)-3-butyl-1(3H)-isobenzofuranone] is an anti-cerebral-ischemia drug. Moderate hepatotoxicity has been observed in clinical applications. One of the major metabolites, 3-N-acetylcysteine-NBP, has been detected in human urine, indicating the formation of a reactive metabolite. We elucidated the formation mechanism of

1. Amine N-sulphotransferase (NST) activity with desipramine (DMI) as substrate was assayed in vitro in various areas of the rat brain. Biosynthesis of 3'-phosphoadenosine-5'-phospho35sulphate (PAPS) from sodium 35sulphate and ATP was also measured by coupling it to the sulphation of

Previous suggestions of CpG-specific apoptotic commitment implied critical epigenetic modulation of housekeeping genes which have canonical CpG islands at 5' promoter regions. Differential housekeeping gene activity however has not been shown. Using a focussed microarray (genechip) of 22 housekeeping genes
The metabolism and cytotoxicity of benzophenone and estrogenic activity of its metabolites have been studied in freshly isolated rat hepatocytes and cultured MCF-7 human breast cancer cells, respectively. The incubation of hepatocytes with benzophenone (0.25-1.0 mM) elicited a concentration- and
The pharmacokinetics of 2,6-dichloro-4-nitrophenol (DCNP) have been studied in the rat. Upon i.v. injection the plasma decay curve of DCNP showed a rapid distribution phase. After 30 min the plasma concentration reached a value that was constant for at least
